Convert datetime64 data type to string

datetime64 needs to be converted to string before viewing using GeoPandas.explore(), otherwise the following error will appear: Object of type Timestamp is not JSON serializable

# created_date, resolution_action_updated_date, closed_date

street_flooding_gdf['created_date'] = street_flooding_gdf['created_date'].dt.strftime('%Y-%m-%d %H:%M:%S')

street_flooding_gdf['closed_date'] = street_flooding_gdf['closed_date'].dt.strftime('%Y-%m-%d %H:%M:%S')

street_flooding_gdf[popup_columns].explore('borough')
